(The funds with retirement dates of 2040 through 2065 are covered in a separate report.) Each fund posted returns that were in line with those of its benchmark after expenses. And each fund except the Institutional Target Retirement Income Fund and the Institutional Target Retirement 2015 Fund surpassed the average return of its peers. Vanguard Target Retirement Funds are designed to reach an allocation of 70% bonds and 30% stocks within seven years after their target dates. Please note, during the third quarter the Institutional Target Retirement 2010 Fund was merged with the Institutional Target Retirement Income Fund, as their asset allocations became identical.

The year in the fund name refers to the approximate year (the target date) when an investor in the fund would retire and leave the work force. The fund will gradually shift its emphasis from more aggressive investments to more conservative ones based on its target date. An investment in a Target Retirement Fund is not guaranteed at any time, including on or after the target date. 2

5 Chairman s Perspective Dear Shareholder, Our investors depend on Vanguard to be a responsible steward of their assets. This includes our obvious responsibilities managing the funds, offering investment perspectives and advice, and assisting with questions and transactions. Bill McNabb Chairman and Chief Executive Officer But because a long-term perspective informs every aspect of our investment approach, we also work on your behalf in less obvious ways, such as by advocating for responsible governance among the companies in which Vanguard funds invest. Vanguard s index funds are essentially permanent owners of thousands of publicly traded companies, and we have a special obligation to be engaged stewards actively focused on the long term. Simply put, we believe that well-governed companies are more likely to perform well over the long run. Although Vanguard has always been an advocate for strong corporate governance, we have expanded our efforts recently as our investor base continues to grow. Our Investment Stewardship team has doubled in size since 2015, and we continue to add analysts, researchers, and operations team members. The team guides our engagement activities and our funds proxy voting by analyzing corporate governance practices in companies around the world. 3

6 Our four Investment Stewardship pillars As we evaluate company responsiveness to governance matters, including environmental and social concerns, we focus on four key areas what we call our Investment Stewardship pillars: The board: A high-functioning, well-composed, independent, diverse, and experienced board with effective ongoing evaluation practices. Governance structures: Provisions and structures that empower shareholders and protect their rights. Appropriate compensation: Pay that incentivizes relative outperformance over the long term. Risk oversight: Effective, integrated, and ongoing oversight of relevant industryand company-specific risks. Guided by these pillars, our Investment Stewardship team conducted more than 950 engagements, or discussions, with company directors and leaders worldwide during the 12 months ended June 30, Market Barometer Average Annual Total Returns Periods Ended September 30, 2017 One Year Three Years Five Years Stocks Russell 1000 Index (Large-caps) 18.54% 10.63% 14.27% Russell 2000 Index (Small-caps) Russell 3000 Index (Broad U.S. market) FTSE All-World ex US Index (International) Bonds Bloomberg Barclays U.S. Aggregate Bond Index (Broad taxable market) 0.07% 2.71% 2.06% Bloomberg Barclays Municipal Bond Index (Broad tax-exempt market) Citigroup Three-Month U.S. Treasury Bill Index CPI Consumer Price Index 2.23% 1.22% 1.30% 4

7 We also cast more than 171,000 votes on behalf of Vanguard funds at more than 18,000 shareholder meetings. Gender diversity on boards and climate risk As we engage with companies, we are devoting increased attention to two specific topics. The first is gender diversity on boards. It s no secret that the right combination of talent, skills, and experience leads to better results, so we pay close attention to how company boards are structured and managed, and how they evolve. In recent years, a growing body of research has demonstrated that greater diversity on boards can lead to improved governance and company performance. We are advocating for boards to incorporate diverse perspectives and experience into their strategic planning and decision-making. One example of our commitment to more diverse boards is our participation in the 30% Club, a global coalition working to increase the representation of women in boardrooms and leadership roles. The second issue is climate risk. We will continue to engage with companies to understand their responses to this risk. Regardless of one s perspective on the issue, the potential is real for changing regulations, demographics, and consumption behavior to affect business results for companies in many sectors. We want to ensure that such business and regulatory risks are sufficiently disclosed so investors can value companies appropriately. In the past year, we have voted for shareholder proposals at several energy companies that called for management to improve its climate risk assessment and planning, and we will consider supporting similar proposals if we believe they are beneficial to long-term shareholder value. When a proposal from a shareholder presents a strong case for change, we re more than willing to fully consider it. And even if the case falls short, these proposals often catalyze a discussion that generates meaningful change over time. In addition to considering activists proposals, we consult research providers and our own network of experts. When we detect material risks to a company s long-term value (such as bad leadership, poor disclosure, misaligned compensation structures, or threats to shareholder rights), we act with our voice and our vote. Our stewardship reflects our mission But we don t act as independent agents with our own agenda. Every time we speak with a company chairman, CEO, or director, we re acutely aware of the role we play in representing the economic interests of more than 20 million Vanguard investors. So you can expect us to speak out when we detect threats to the economic interests of our shareholders. 5

8 We take positions on these matters not because they are inherently good or noble but because they are tied to the long-term economic value of your funds investments. You trust us to represent your interests across the globe. You can be confident we act on that responsibility with the seriousness and dedication it deserves. To learn more about our Investment Stewardship program, including how our funds have voted, visit vanguard.com/investment-stewardship/. As always, thank you for investing with Vanguard. Sincerely, F. William McNabb III Chairman and Chief Executive Officer October 13,

17 Institutional Target Retirement Income Fund Notes to Financial Statements Vanguard Institutional Target Retirement Income Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund follows a balanced investment strategy by investing in selected Vanguard funds to achieve its targeted allocation of assets to U.S. and international stocks, and U.S. and international bonds. Financial statements and other information about each underlying fund are available on vanguard.com. A. The following significant accounting policies conform to generally accepted accounting principles for U.S. investment companies. The fund consistently follows such policies in preparing its financial statements. 1. Security Valuation: Investments are valued at the net asset value of each underlying Vanguard fund determined as of the close of the New York Stock Exchange (generally 4 p.m., Eastern time) on the valuation date. 2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund s tax positions taken for all open federal income tax years (September 30, ), and has concluded that no provision for federal income tax is required in the fund s financial statements. 3. Distributions: Distributions to shareholders are recorded on the ex-dividend date. 4. Credit Facility: The fund and certain other funds managed by The Vanguard Group ( Vanguard ) participate in a $3.1 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund s board of trustees and borne by the funds in which the fund invests (see Note B). Any borrowings under this facility bear interest at a rate based upon the higher of the one-month London Interbank Offered Rate, federal funds effective rate, or overnight bank funding rate plus an agreed-upon spread. The fund had no borrowings outstanding at September 30, 2017, or at any time during the period then ended. 5. Other: Income and capital gain distributions received are recorded on the ex-dividend date. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold. 15

18 Institutional Target Retirement Income Fund B. In accordance with the terms of a Funds Service Agreement (the FSA ) between Vanguard and the fund, Vanguard furnishes to the fund investment advisory, corporate management, administrative, marketing, and distribution services at Vanguard s cost of operations (as defined by the FSA). These costs of operations are allocated to the fund based on methods and guidelines approved by the board of trustees. The FSA provides that expenses otherwise allocable to Vanguard funds-of-funds may be reduced or eliminated to the extent of savings realized by the underlying Vanguard funds by virtue of being part of a fund-of-funds. Accordingly, all expenses for services provided by Vanguard to the fund and all other expenses incurred by the fund during the period ended September 30, 2017, were borne by the underlying Vanguard funds in which the fund invests. The fund s trustees and officers are also trustees and officers, respectively, of the underlying Vanguard funds, as well as directors and employees, respectively, of Vanguard. C. Various inputs may be used to determine the value of the fund s investments. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities. Level 1 Quoted prices in active markets for identical securities. Level 2 Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.). Level 3 Significant unobservable inputs (including the fund s own assumptions used to determine the fair value of investments). Any investments valued with significant unobservable inputs are noted on the Statement of Net Assets. At September 30, 2017, 100% of the market value of the fund s investments was determined based on Level 1 inputs. D. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes. These differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes. For tax purposes, at September 30, 2017, the fund had $2,382,000 of ordinary income and $395,000 of long-term capital gains available for distribution. At September 30, 2017, the cost of investment securities for tax purposes was $4,750,131,000. Net unrealized appreciation of investment securities for tax purposes was $280,051,000, consisting entirely of unrealized gains on securities that had risen in value since their purchase. 16

19 Institutional Target Retirement Income Fund E. Capital shares issued and redeemed were: Year Ended September 30, Shares Shares (000) (000) Issued 95,617 65,895 Issued in Connection with Acquisition of Vanguard Institutional Target Retirement 2010 Fund 88,677 Issued in Lieu of Cash Distributions 2,657 1,381 Redeemed (48,625) (12,038) Net Increase (Decrease) in Shares Outstanding 138,326 55,238 At September 30, 2017, one shareholder was the record or beneficial owner of 29% of the fund s net assets. If the shareholder were to redeem its investment in the fund, the redemption might lead to the realization of taxable capital gains. F. On July 21, 2017, the fund acquired all the net assets of Vanguard Institutional Target Retirement 2010 Fund pursuant to a plan of reorganization approved by the funds board of trustees. The purpose of the transaction was to combine two funds with comparable investment objectives. The acquisition was accomplished by a tax-free exchange of 88,677,000 shares of the fund for 89,056,000 shares of the Vanguard Institutional Target Retirement 2010 Fund outstanding as of the close of business on July 21, The Vanguard Institutional Target Retirement 2010 Fund s net assets as of the close of business on July 21, 2017, of $1,874,542,000, including $111,122,000 of unrealized appreciation, were combined with the fund s net assets. The net assets of the fund immediately before the acquisition were $2,936,988,000. The net assets of the fund immediately following the acquisition were $4,811,530,000. Assuming that the acquisition had been completed on October 1, 2016, the beginning of the fund s reporting period, the fund s pro forma results of operations for the year ended September 30, 2017, would be: ($000) Net Investment Income 86,895 Realized Net Gain (Loss) 10,268 Change in Unrealized Appreciation (Depreciation) 146,955 Net Increase (Decrease) in Net Assets Resulting from Operations 244,118 Because the combined funds have been managed as a single integrated fund since the acquisition was completed, it is not practical to separate the results of operations of Vanguard Institutional Target Retirement 2010 Fund that have been included in the fund s statement of operations since July 21,

29 Institutional Target Retirement 2015 Fund Notes to Financial Statements Vanguard Institutional Target Retirement 2015 Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund follows a balanced investment strategy by investing in selected Vanguard funds to achieve its targeted allocation of assets to U.S. and international stocks, and U.S. and international bonds. Financial statements and other information about each underlying fund are available on vanguard.com. A. The following significant accounting policies conform to generally accepted accounting principles for U.S. investment companies. The fund consistently follows such policies in preparing its financial statements. 1. Security Valuation: Investments are valued at the net asset value of each underlying Vanguard fund determined as of the close of the New York Stock Exchange (generally 4 p.m., Eastern time) on the valuation date. 2. Futures Contracts: The fund uses stock and bond futures contracts to a limited extent, with the objectives of maintaining full exposure to the market and maintaining its target asset allocation. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of investments held by the fund and the prices of futures contracts, and the possibility of an illiquid market. Counterparty risk involving futures is mitigated because a regulated clearinghouse is the counterparty instead of the clearing broker. To further mitigate counterparty risk, the fund trades futures contracts on an exchange, monitors the financial strength of its clearing brokers and clearinghouse, and has entered into clearing agreements with its clearing brokers. The clearinghouse imposes initial margin requirements to secure the fund s performance and requires daily settlement of variation margin representing changes in the market value of each contract. Futures contracts are valued at their quoted daily settlement prices. The notional amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Assets and Liabilities as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses). During the year ended September 30, 2017, the fund s average investments in long and short futures contracts represented less than 1% and 0% of net assets, respectively, based on the average of the notional amounts at each quarter-end during the period. The fund had no open futures contracts at September 30, Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund s tax positions taken for all open federal income tax years (September 30, ), and has concluded that no provision for federal income tax is required in the fund s financial statements. 4. Distributions: Distributions to shareholders are recorded on the ex-dividend date. 5. Credit Facility: The fund and certain other funds managed by The Vanguard Group ( Vanguard ) participate in a $3.1 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the 27

30 Institutional Target Retirement 2015 Fund fund s board of trustees and included in Management and Administrative expenses on the fund s Statement of Operations. Any borrowings under this facility bear interest at a rate based upon the higher of the one-month London Interbank Offered Rate, federal funds effective rate, or overnight bank funding rate plus an agreed-upon spread. The fund had no borrowings outstanding at September 30, 2017, or at any time during the period then ended. 6. Other: Income and capital gain distributions received are recorded on the ex-dividend date. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold. B. In accordance with the terms of a Funds Service Agreement (the FSA ) between Vanguard and the fund, Vanguard furnishes to the fund investment advisory, corporate management, administrative, marketing, and distribution services at Vanguard s cost of operations (as defined by the FSA). These costs of operations are allocated to the fund based on methods and guidelines approved by the board of trustees. The FSA provides that expenses otherwise allocable to Vanguard funds-of-funds may be reduced or eliminated to the extent of savings realized by the underlying Vanguard funds by virtue of being part of a fund-of-funds. Accordingly, all expenses for services provided by Vanguard to the fund and all other expenses incurred by the fund during the period ended September 30, 2017, were borne by the underlying Vanguard funds in which the fund invests. The fund s trustees and officers are also trustees and officers, respectively, of the underlying Vanguard funds, as well as directors and employees, respectively, of Vanguard. C. Various inputs may be used to determine the value of the fund s investments. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities. Level 1 Quoted prices in active markets for identical securities. Level 2 Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.). Level 3 Significant unobservable inputs (including the fund s own assumptions used to determine the fair value of investments). Any investments valued with significant unobservable inputs are noted on the Statement of Net Assets. At September 30, 2017, 100% of the market value of the fund s investments was determined based on Level 1 inputs. 28

31 Institutional Target Retirement 2015 Fund D. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes. These differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes. The fund used a tax accounting practice to treat a portion of the price of capital shares redeemed during the year as distributions from net investment income and realized capital gains. Accordingly, the fund has reclassified $5,501,000 from undistributed net investment income and $251,000 from accumulated net realized gains to paid-in capital. For tax purposes, at September 30, 2017, the fund had $94,715,000 of ordinary income and $3,642,000 of long-term capital gains available for distribution. At September 30, 2017, the cost of investment securities for tax purposes was $6,994,329,000. Net unrealized appreciation of investment securities for tax purposes was $611,907,000, consisting entirely of unrealized gains on securities that had risen in value since their purchase. E. Capital shares issued and redeemed were: Year Ended September 30, Shares Shares (000) (000) Issued 105, ,151 Issued in Lieu of Cash Distributions 5,871 1,623 Redeemed (54,838) (33,396) Net Increase (Decrease) in Shares Outstanding 56, ,378 At September 30, 2017, one shareholder was the record or beneficial owner of 31% of the fund s net assets. If the shareholder were to redeem its investment in the fund, the redemption might lead to the realization of taxable capital gains. 29
